VAPORIZING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Application filed September 26, 1922.

device also contemplates mixing the vapor with heated air.

The object of the invention is to provide a device of the character set forth-which can be readily attached to aninternal combustion engine without drilling or tapping holes in any of the parts thereof and which is capable of supplying steam to the intake manifold of the engine, said steam being formed by heating water automatically supplied to a vaporizing device and the vaporizing. device being supplied with heat from the exhaust manifold of the engine to which it is attached.

The object of the invention is further to provide mechanism whereby the water from a container may be allowed to flow to the vaporizing device or may be shut off therefrom, said mechanism being operated conveniently from the dash of an automobile upon which the device as a whole is mounted.

The invention further contemplates supplying means for regulating the amount of water which may flow from the container to the vaporizing device.

Referring to the drawings Figure 1 is a sectional elevation partly broken away, illustrating my improved vaporizing device attached to the exhaust and intake manifold of an internal com bustion engine, the said figure also illustrating a portion of the dash of an auto mobile upon which the engine is located.

Fig. 2 is a detail side elevation of a portion of the mechanism for operating one of the valves of the device, the same being viewed in the opposite direction from that in which Figure 1 is viewed.

Fig. 3 is a detail sectional elevation taken on line 33, Figure 1, and illustrating the manner in which the vaporizing device is Serial No. 590,746.

attached to the exhaust manifold of the engine.

Like numerals refer to like parts throughout'the several views of the drawings.

In the drawings, 5 is the exhaust manifold of an internal combustion engine and 6 the intake manifold of said engine. T is a portion of the carbureter of any suitable construction and 8 is the dash of the auto mobile upon which the engine is mounted. 9 is a vaporizing member comprising an open receptacle without cover 10 provided with a chamber 11 opening out of the bottom of said receptacle. The receptacle 10. has semi-circular recesses 12 in the opposite 1y disposed walls thereof so that the receptacle fits loosely upon the exhaust manifold 5 upon which it is placed bottom upward and to which it is securely clamped by a U-shaped clamp 13 and nut 14. The semi-circular recesses '12 of the receptacle 10 do not form an air tight fit upon the exhaust manifold 5, so that in the operation of the device a certain amount of air can pass into the chamber 11.

A container 15 for water has a base 16 which is fastened by screws 17 to the top of the receptacle 10. A pipe 18 and fitting 19 connect the container 15 to the chamber 11. The fitting 19 may be considered as forming a part of the pipe 18 and is provided with passages 20 through which the water flows from the container 15 to the pipe portion 18 and into the chamber 11. The said fitting isprovided with a plunger valve 21 slidably mounted therein and adapted to either entirely close the passage 20 or to open it, said plunger being slidably mounted in the sleeve 22, fastened to the fitting 19 and to an car 23 on the container 15. A collar 24 is fastened to the plunger 21 and a spring 25 encircles the plunger 2.1,. the lower end thereof resting against the collar 2 1 and the upper end thereof against a bracket 26 which is fastened to the ear 23 by a nut 27 having screw-threaded engagement with the sleeve 22. A lever is pivoted at 29 to the ear 23 and is connected at one end thereof by a link 30 to the collar Qt and at the other end thereof is connected by a link 31 to a pin 32 eccentrically mounted on a lever 33 which is pivoted at 3 1 to a bracket 35 fast to the dash 8.

The lever 33 is provided with two shoulders 36 and 37, the shoulder 36 being adapted to strike against the bracket which is fastened to the dash 8, when the lever is in its lowered position. lVhen the lever 33 is operated by means of the handle 38 thereon, so that said handle projects upwardly, the shoulder 37' abuts against the bracket 35 on the dash 8 and the lever 28 is then tipped from the position illustrated in Figure 1. to the position illustrated in Fig. 2, and by thus tipping said lever the link 30 is moved upwardly pushing the collar 24 upwardly and compressing the spring 25, and at the same time the plunger valve 21 is raised so that the passage 20 is fully opened to allow water to pass from the container 15 downwardly through the fitting 19 and pipe 18 and into the chamber 11.

In order to regulate the amount of water which can flow into the chamber 11 during any given period of time, that is, so that it will pass into the chamber 11 drop by drop, a needle valve 39 is provided which has screw-threaded engagen'ient with the fitting 1.9 and is locked in position by alock nut 40, so that by rotating the screw-threaded valve 39 it may be raised or lowered to open the passage 20. more or less as may be desired.

The vaporizing member 9 is connected by a pipe 4lto a lug 42 extending downwardly from a collar 43 and said lug 42 is provided with a passage 44 which registers with the pipe 41 and opens into the bore 45 of the collar 43. The collar 43 is clamped in position between two gaskets 46 and 47 and the adjacent ends of the carburetor outlet 48 and the intake manifold inlet 49. I

The general operation or the device hereiubet'o-re specifically described is as follows ater is placed in the container 15, the

needle valve 39 being adjusted to allow the desired amount of water to drip into the chamber 11 of the receptacle 10. The plunger valve 21 is opened by moving the handle 38 of the lever 37 so as to rotate said lever upwardly until the shoulder 37 abuts against a portion of the bracket 35 on the dash 8 This will move the lever 28 from the position illustrated in Figure 1 to that illustrated in Fig. 2 and will allow the water to pass drop by drop from the container 15 into the chamber 11.

Assuming the engine to be in operation, then the exhaust pipe 5 will be very hot and a drop of water as soon as it enters the chamber 11 will be changed to steam or vapor and at the same time a certain amount of air will enter the chamber 11 between the exhaust pipe and the semi-circular recesses 12 in the receptacle '10. This air will also become intensely heated and mixing with the steam will be drawn down the pipe 41 through the passage 44 and will enter the intake manifold adjacent the outlet of the carburetor where it will be intermingled with the gases from the carburetor, and being heated to a high degree will raise the temperature of the gases from the carbureter and will pass through the intake manifold inthe usual '7 manner to the cylinders of the engine.

It is found that the mixing of heated air and steam with the gases from the carburetor produces a very beneficial effect, increasing the mileage which can be. obtained from a.

certain amount of gas supplied to the engine.

I claim:

A. vaporizing device adapted to be 'attached to'the manifold or outlet of an internal combustion engine and comprising an open receptacle without cover adapted to be placed bottom upward on said manifold, the oppositely disposed walls of said receptacle being provided with recesses, the

and close the same and to hold it in locked position and means to convey vapor out of said receptacle for use in the engine.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses;
